Abstract

Un système et des méthodes d'atténuation d'interférence co-site et trajets multiples sont présentés. Un signal de réflexion est reçu d'au moins une surface d'aéronef par un capteur à proximité d'une antenne de réception, et une antenne réseau conformée à réflexion en phase couplée à au moins une surface d'aéronef est configurée pour orienter le signal de réflexion. Le signal de réflexion est orienté à l'aide de l'antenne réseau conformée à réflexion en phase en vue de réduire une amplitude du signal de réflexion à l'antenne de récepteur en fonction du signal de réflexion reçu par le capteur.
